Retainer for window regulators



Patented Aug. 12, 1936 TJ'ZZJ59 CLARENCE E. RIOKEL, GRANT W. CRAMER, AND HOWARD B. HASKINS, OF TOLEDO, OHIO, ASSIGNORS, TO TEE DURA COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO RETAINER FOR \VINDOW REGULATORS Application filed April 18,

The invention relates to retainers for window regulators and one of its objects is to so construct the retainer that it may be effectively secured in place and at the same time provides for locating the lifter element of the window regulator in close proximity to the window, thereby decreasing the bending moment exerted upon the lifter elementby the window and permitting a decrease in the necessary width of chamber for receiving the window. Another object is to so construct the Window that rattling of the parts is prevented. Further objects of the invention reside in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 is an interior side elevation part- 1y broken away, of a portion of a motor vehicle door having applied thereto a window regulator retainer embodyingour invention; Figure 2 is a cross section on the line 2-2 of Figure 1;

Figure 8 is a View similar to Figure 1 showing a modified construction;

Figure 4 is a cross section on the line l& of Figure-3.

The retainer embodying our invention operatively connects in the present instance a pivotal lifter arm 1 of a window regulator with the window 2, which latter is in the nature of a glass and is vertically movable in the usualguide ways from a position closing V the opening to a position within the chamber below the opening. This window has at its lower edge the metallic channel-shaped clip 3 which embraces and is secured to the glass.

4 is the body of the retainer in the nature of a flanged sheet metal plate having the lateral flange 5 and the depending flange 6. This depending flange preferably terminates at its lower edge in the lateral reinforcing flange 7. 8 is the pin of the retainer extending transversely of and rigidly securec to the lifter arm 1 and having at its outer end the head 9. This pin extends. through the depending flange 6.

For preventing rattling of the parts, we

have provided the washer 10 encircling the 1927. Serial No. 184,691.

pin and slidably bearin upon the inner side of the depending flange 6 and the lifter arm.

For the purpose of providing suflicient bearing between the lateral flange 5 of the retainer and the base of the clip 3 to effectively secure the retainer to the clip and also for the purpose of locating the lifter arm 1 in close proximity to the inner side of the clip, the depending flange 6 of the retainer has the intermediate portion 12 which is offset laterally outwardly relative to the point of connection of the depending flange to the lateral flange and this oifset portion is provided with the longitudinally extending slot 13 through which the pin 8 extends. The washer 10 is made concave-convex and the coil spring 11 is made collapsible, it being a helical spring permitting of the nesting of one convolution within another. The oflset portion 12 has at the upper and lower edges of the slot 13 the lateral flanges 1% which serve to reinforce the retainer and to provide bearings for the pin. The metal at the upper and lower inner edges of the slot is also rounded and the convex side of the washer slidably bears upon these rounded surfaces. The head 9 of the pin provides shoulders slidzltplyengaging the edges of the lateral flanges It will be seen that with this arrangement an extended bearing may be secured between the lateral flanges 5 and the clip 3 to provide for eifectively spot welding or riveting the retainer to the clip. It will also be seen that the arrangement provides for locating the lifter arm in close proximity to the inner side of the clip and prevents rattling of the parts. By reason of the decreased width, the necessary width of the chamber for receiving the window may be decreased.

In the modification shown in Figures 3 and t, the parts have the same general arrangement but instead of providing an enlargement at one end of the slot in the retainer, as shown in Figures 1 and 2, the head 15 of the pin 16 is flatted as at 17 to provide for passing the pin through the longitudinal slot 18 of the retainer. The pin is preferably secured to the lifter arm in such a position that with the lifter arm in a position beyond its normal limits of travel the pin may be passed through the slot.

What we claim as our invention is:

1. A retainer for operatively connecting a window regulator lifter element to a window, including a flanged plate having alateral flan e secured to the window and a depending flange, said depending flange having a slotted portion offset laterally outwardly rela tive to the point of connection of said depending flange to said lateral flange, a pin secured to the lifter element and extending through the slot, a coil spring encircling said pin for forcing the lifter element away from said depending flange, and means upon said pin and engageable with the outer side of said depending flange for holding the parts in engagement.

2. A retainer for operatively connecting a window regulator lifter element to a window, including a flanged plate having a lateral flange secured to the window and a depending flange having a portion ofl'set laterally outward relative to the point of connection of said depending flange to said lateral flange and formed with a longitudinally extending slot with lateral flanges at the upper and lower edges of the slot, a pin secured to the lifter element and extending through the slot and bearing upon said last mentioned lateral flanges, a coil spring encircling said pin for forcing the lifter element away from said depending flange, and means upon said pin providing shoulders engageable with the outer sides of said depending flange for holding the parts in engagement.

3. A retainer for operatively connecting a window regulator lifter element to a window with a metallic channel-shaped clip at its lower edge, said retainer including a pin extending transversely of and secured to the lifter element and having a head at its upper end, a flanged plate having a lateral flange secured to the base of said channel-shaped 7 clip and a depending flange having a portion ofl'set laterally outwardly relative to the point of connection of said depending flange to said lateral flange, said ollset portion having a longitudinally extending slot with lateral flanges at the upper and lower edges of the slot, said pin extending through the slot and adapted to slidably engage said last mentioned flanges and the head upon said pin providing shoulders adapted to bear upon the edges of said last-mentioned flanges, a washer having a convex face bearing upon said offset portion at the upper and lower inner edges of the slot, and a coil spring encircling said pin and abutting said washer and lifter element for yieldably forcing the lifter element away from said depending flange.

l. A retainer for operatively connecting a window regulator lifter element to a window, including a body secured to the window. a pin connecting the lifter element to said body,

and a collapsible coil spring for yieldingly forcing the lifter element away from said body.
